  • Patent number: 6745473
    Abstract: A cable sheathing slitter attachment for a wire stripper tool. The cable sheathing slitter attachment is preferably integrally formed of sheet metal and a blade member and a guard member. The blade member includes a blade portion having first and second oppositely facing knife-edges and a mounting portion having an opening that facilitates the mounting of the blade member to a jaw of the wire slitter tool. The guard member includes a mounting portion with a hole therethrough and a U-shaped guard portion. A fastener passes through the hole in the mounting portion of the guard member, the elongated opening in the mounting portion of the blade member and through the hole in the respective jaw to mount the guard and blade members to the jaw of the wire stripper tool. The guard is rotatable with respect to the knife-edges to expose the knife-edges when it is desired to use the same for the slitting of non-metallic sheathed cables.

  • Patent number: 6247235
    Abstract: A combined sheathing stripper and sheathing cutter tool for non-metallic sheathed cable. The tool includes a body that is used to retain a slitter-blade and a cutter-blade. The slitter-blade includes a first knife edge that is located on a first side of the tool body when the blade is mounted in the body and a second knife edge that is located on the other side of the tool body. The knife edges are oriented such that the first knife edge may be used for slitting a cable sheathing by pushing the tool while the first knife edge is engaging the sheathing and the second knife edge may be used for slitting a cable sheathing by pulling the tool while the second knife edge is engaging the sheathing. An opening is provided within the body and the cutter-blade includes a knife edge that faces the opening when the cutter-blade is mounted in the body. A cable sheathing that has been slit may be passed through the opening and cut off using the cutter-blade.
